Best Practices when using Onslaught FastCap Microencapsulated Insecticide:

Dilute with water only. The suspension is only intended for dilution in water, not oil.

Test the surface first. Onslaught FastCap may be sprayed on any surface that will not be stained by water. If you are concerned about staining or are not sure if a surface is water safe, test the surface by spraying a small amount in an inconspicuous area before making a broad application.

Mixing tip. Shake Onslaught FastCap bottle well prior to mixing. Clean spray equipment before using or diluting Onslaught FastCap. For dilution, add half the required water to spray tank, then add the appropriate amount of Onslaught FastCap. Agitate the mixture, and then slowly add the remainder of the water. Agitate the spray thoroughly before using and also occasionally during use to ensure dispersion. If you use a spray filter screen, they should be 50 mesh or larger.

Use Onslaught FastCap as part of an IPM program. Tank mix Onslaught FastCap with an IGR such as NyGuard IGR Concentrate to break the insect growth cycle and control future emerging insect populations. Do not apply Onslaught FastCap as a fog or space spray. Fog first with a product such as Riptide Water-Based Pyrethrin ULV to get the quick knockdown action of the fog followed by a surface application of Onslaught FastCap for residual control.

    5 of 5 Stars  Initial review on effectiveness vs scorpions
    By Scott on March 2, 2014
    Verified Purchase

    Main Target Pest- Bark Scorpion I have used Cykick, Cyper WP, Bifen IT, Demand, and suspend polyzone for scorpion control here in AZ. Cyckick seems to be the best so far. I don't have a huge problem with them, but I have found the occasional one indoors. I black light ~ every night once the temp is warm enough at night to monitor activity. I spray onslaught for the first time in mid feb. I went out 1 week later and found a dead one against the cinder block wall. I don't normally see this even with Cykick, so I got lucky or this stuff works well. It is also cheaper than Cykick per finished gallon once the price drop to _ 60/ bottle. I will use until gone and see how well it control scorpions this summer.

    Your web site is user friendly and easy to navigate. The cost of your products are at or lower than others sites. I did find a sprayer on another site that was lower and I sent you the link. You then lowered the price and I purchased it along with insecticide. By the way, Onslaught Fastcap Spider Insecticide does what it says it will do!! Great product! Great company! I could'nt ask for a better outcome.

    By Dana on September 23, 2013
    Verified Purchase

    I would really recommend this product. I got it for spiders & scorpions both inside & outside the house. I've only used inside so far but it works. I don't know if this stuff calls out the scorpions but 3 are dead so far. I didn't even know i had that many scorpions around. I live in a new development in a heavily wooded area so I expected critters, never scorpions though.

  • 5 of 5 Stars  Very Satisfied with Kill and Residual
    By Tom on November 25, 2014

    Our property backs up to open desert, so scorpions were a serious problem. We tried a couple of hardware store solutions but they were ineffective. FastCap was clearly superior. We saw numerous dead bugs during the weeks following application, so no question about the immediate kill. The residual also worked well, as we spotted only an occasional scorpion at the 3 month reapplication date.

  • 5 of 5 Stars  EXCELLENT PRODUCT
    By Mike on November 7, 2014

    We live in a National Forest surrounded by heavy forest. After years of paying $95+ per regular scheduled visits by a pest control company, we still had scorpions inside of our home. We knew something had to be done better than a local pest control service. After web searching, we came across this company and the product Onslaught. One application of Onslaught (2tbs) per gallon wiped out the scorpions & all other creeping critters! Best pest control product we have purchased. We cancelled our pest control service! We applied Onslaught on fire ants just to see what the results would be...killed them all dead within a few minutes! We highly recommend this product.

    By Eddie on October 14, 2014

    Our son bought an older home that had not had a pest control agreement on it for a few years. They had a terrible scorpion problem. After treating with Onslaught FastCap they have only seen a couple over several months. This is a wonderful treatment for all kinds of bugs. We have made a second order. We don't want to run out of this.

January 28, 2014 Michael from Lake Oconee, Ga asked:

QOnslaught FastCap Spider and Scorpion Insecticide vs. Demand CS?
I have had good results with Demand CS for controlling mosquitoes, wasps, dirt doppers and, to a lesser degree, spiders in our outdoor living areas and around the overhangs of our house. It appears from the produce descriptions that the Onslaught FastCap Spider and Scopion product may provide a more targeted control for spiders. Might I see more effective control of spiders around the exterior of the house if I were to use BOTH products (Demand CS and Onslaught) at the same time?

AThese products should not be mixed together. There is no valid reason to mix Demand CS and Onslaught FastCap Spider and Scorpion together.  Demand CS is a synthetic pyrethroid and Onslaught FastCap already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

May 19, 2013 L. from Las Vegas, Nevada asked:

QOnslaught versus Demand, Cykick or Cyzmic for Scorpions
To eliminate scorpions, is Onslaught the strongest, most effective insecticide to spray indoors and out? My treatments have included Demand, Cysmic and Cykick CS and Aerosol (aerosol for knockdown and cracks and crevices) and now am hearing about Onslaught FastCap Spider and Scorpion insecticide and wonder if it is stronger or the strongest. My thought is, if I'm spending money on insecticide and investing time to treat my home to ward off these horrible scorpions that I fear, I want the most effective product on the market. I'd rather purchase and concentrate on the best! Thanks.

AThe Onslaught FastCap would definitely be the best option for your needs. It is specifically formulated to better target spiders and scorpions with a more thorough and long lasting coverage for these hard to kill pests. Keep in mind, no matter what product you are using for scorpions, you have to create a wider barrier for them than any other pest around your home. For general insects you would treat with a barrier around the foundation 2 feet up and 2 feet out. With scorpions you should be doing 2-3 feet up and 6-10 feet out on the ground. Also make sure to treat any landscape areas around your home that they would be prone to hiding in ie: mulch, bark, landscape timbers, rocks etc. You can review more information for protecting your home from scorpions in our article on Scorpion Control.

QIs there a benefit to Onslaught FastCap vs. regular Onslaught?
I've been using regular Onslaught for residual hornet, ant, and earwig control. Is there a benefit to switching from regular Onslaught to FastCap? Either way, I need to buy another bottle, and want to make sure I'm getting the best.

AThe biggest difference of Onslaught Fastap and Onslaught are the Onslaught Fastcap  combines a one of a kind formulation is made of Exponent brand synergist, Esfenvalerate, and Prallethrin. So Onslaught Fastcap offers an even quicker more intense knockdown.

August 16, 2014 Betty from Princeton, Tx asked:

QWhat is the best way to get rid of scorpions?
Tried several ways. They are getting bigger and seen more often.

A

Onslaught Fast Cap contains different active ingredients including PBO. PBO gives the Fast Cap an extra kick in killing more quickly. It is microencapsulated and provides a long lasting residual and making it easier for the scorpion to pick up. Getting rid of Scorpions requires a combination of both chemical and non-chemical measures. Think of non-chemical measures (such as vacuuming, sanitation, harborage removal, and exclusion) as limiting or removing conditions that contribute to the infestation. These measures are largely preventative. The next step is to come in with the real ammunition-chemical pesticides-that do the job of physically wiping out an infestation. Please refer to the article below for more information.

July 10, 2014 James from Crowley asked:

QIf I spray my house with Onslaught FastCap and it rains within 30 mins will it still work ?

A Onslaught FastCap as well as many other liquid insecticides only need about 30 minutes to dry. Once dry, they can hold up to rain rather well.  However, it is much easier for the product to bond to porous surfaces like concrete and siding then grass and your lawn. You may want to apply again just to be safe when there is not rain in the forecast for at least 24 hours

QHow Safe is Onslaught Fast Cap Spider and Scorpion Insecticide
I am looking for a product that is non toxic that can be used indoors on baseboards and outdoors as well to kill mainly spiders. The company that has sprayed for me before uses a product that is safe for use restaurants, day care, and hospitals. I believe it is derived from Chrysanthemums.

A Onslaught FastCap Spider and Scorpion Insecticide is not organic, but is safe for children and pets after the treated area has dried. You may also be interested in Alpine WSG.
